★ Contract unverified on Etherscan/Sourcify
USDD (Decentralized USD)'s assessment for RD-F-046 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
[U3 RECONCILED: red→yellow] The canonical Ethereum ERC-20 is 0x4f8e5de400de08b164e7421b3ee387f461becd1a — source-VERIFIED on Etherscan (Exact Match, Solidity 0.6.12, 5,863 holders). 0x8EbdcF3d843E3A96137E84117C7989C883cE6127 (84 holders, unverified) is a low-adoption secondary/test deployment, NOT the canonical USDD contract; the prior red was scored against the wrong address. Canonical BSC BEP-20 (0x392004BEe213F1FF580C867359C246924f21E6Ad) source is also available on BscScan. The TRON canonical TRC-20 (TPYmHEhy5n8TCEfYGqW2rPxsghSfzghPDn, 92.45% TVS) source is inaccessible via Tronscan — this is an infrastructure block (our fetch infra failing), NOT protocol opacity; TRON contracts are normally source-published on Tronscan. Yellow (not green) because the dominant chain (TRON, 92.45% TVS) source cannot be confirmed via the standard toolchain due to infra gap. Green would require Tronscan access or an alternative TRON source mirror.
